BOOT JACK.

i UNITED STATES PATENT OFFI E BOOT-JAC Q SP CIFICATION forming part of Letters Patent No. 254,816, dated March 14, 1882. Application filod December 6, 1881. (No model.)

T0 all whom it may conccrn Be it known th at I, KASPER J. GREENWALD,

a citizen of the United States, residing in the city of Newark, Essex County, New Jersey, have inven ted certain new and useful Im provements in Boot-Jacls, fully described and represented in the following specification and the accompanyin g dra-wings, formin g a part of the Same. i

My invention relates to an improvement in boot-jacks; and it consists in the combination,

is a sectional view on the under sideof the' same, but showing a modified construction. Fig. 3 Is a perspecttve side view of the same;

' and Fig. 4: is a perspective view of the under side of the jaws, showing a further modification.

The lining shown inthe drawings has proved the best adapted to the purpose, and consists of a steel Strip, w, having a rubber tube, y, drawn tightl y over it, so as to present a powerful griping-surfaee combined with great elasticity. l

A is the body of the jack; B, thejaws; C, the cleat to rest upon the floor; D, the lining; E, the re-en forcin g Springs; F, clamps forsecu'ring the front ends of the Same; G, notches in the body at the base of thejaws for the rear ends of the Springs E to play in, and H Caps applied to the front ends of the jaws to Secure the lining D in place.

The lining forms an open loop within the jaws to receive the boot, and is bent over the front ends of the jaws and fastened by a nail, ct. The caps H prevent the nails from pulling out and form a better finish, and may be made of any metal, wrought or cast, so as to cover the ends of thejaws. They are shown in the drawings Secured by tacks I). i

The Springs E are, shown in Fig. 1 riveted es G. 'In Fig. 2 the Springs are shown unsecured to the loop D by any rivet, and having their front ends unprovided with any clamps F, but having their front ends carried around the ends ofthejaws, beneath the bent ends of the lining, and secured by the same nail, a. When thus arranged the lining needs some other' brace vertioally to resist the upward pull of the boot, and such a brace is shown in Fig. 4 in the form of an upright link, I, I'iveted to the rear end of the loop at h, and fastened to the cleat near the floor by a sorew or nail,e. When thus braced the lining may be used, if desired, without the Springs E, as shown in Fig. 4.

From the above description it Will be seen that the linin g D is peeuliarly adapted. to yield to theshapes of boots of various siZeS by reason of its being unrestricted in its lateral movement, while the means descrihed show that it can be brace'd in any required direction without diminishing this quality.

Having shown a number of ways for securing the ttexible and elastic lining, it is obvious that the same could be arranged to press Inerelyupon the Sides of the boot by cutting out the bottom of the loop, as from m to n in Fig. 1, and relying upon the Springs E to support the lining Vertically.

I am aWare thatjaws formed upon the ends ofjointed levers have been made, and may be considered as yielding surfaces adapted to fit boots of different siZes. Claim a yieldi ng-jaw, but a yielding lining to a fixed or stationary jaw; and not merely that, but one having a griping-surface, which I believe no lever-jaws have been provided with.

I am also aware that a strip of rubber has been fitted into a groove formed inside the jaWs; but such alining has no such adaptability as mine to boots of different sizes by reason of its flexibility,'it 'possessing merely a limited degree of compressibility. Ido not therefore Claim a rubber lining, broadly; but, having shown the construction of my yieldingor spring lining, the difference between the inventions referred to and my own will be readily Observed, [ny lining obviously deriving its yielding nature from its internal band of elastic metal and its griping quality from the softrubber coating. Such coating may, if preferred, be cemented to the inside Only of the loop, and

I do not, however,

- Other materials-:IS ieather, &c.-may be sub- Stituted for rubber, it' possessing a griping Character. v

To increase or adjust the force of the Springs E, I provide set-screwsf, inserted in the body of the jack, SO as to penetrate the Sides of the notehes G, in which the renr endsof the Springs play. By tnrning the screws the ends of the Springs can be forced nward and their pressure upon the eides of the loop inceased at pleasure.

I therefore Claim my iuvention as foilows:

In a boot-jack, a flexible Iiuing for the jaws,

consisting of a rnhber-covered metallic Sprin g, having its end secnred to the front ends of the jaws, combined With meansfor Seeuring the lining within the jaws at a fixed level, substantialiy as Set forth.

In testimony whereof I have hereunto Set my hand in the presence of two suhscribing 20 WitneSSeS.
